Aflatoxin B1 (AFB1) is an unavoidable environmental toxin. The accumulation of AFB1 and its metabolites in the liver poses a threat to both human and animal health. Curcumin exhibits anti-oxidative, anti-tumor, and anti-inflammatory properties. There is no report on the mechanism regarding how curcumin relived liver necroptosis in chickens induced by AFB1 based on the regulatory network of ceRNA.

Aflatoxin B1, a major global food safety concern, is produced by toxigenic fungi during crop growing, drying, and storage, and shows increasing annual prevalence. This study aimed to detect aflatoxin B1 in chili samples using ATR–FTIR coupled with machine learning algorithms. We found that 83.6% of the chili powder samples were contaminated with Aspergillus and Penicillium species, with aflatoxin B1 levels ranging from 7.63 to 44.32 µg/kg.

Ochratoxin A (OTA) is one of the mycotoxins in the agriculture and livestock sectors. The poultry sector suffered from significant economic losses due to the adverse impacts of OTA on the growth rate, feed conversion ratio, and livability. Thus, the present investigation aimed to determine the impact of chamomile essential oil supplementation against OTA toxicity in growing quails. 360 one‐week‐old growing quails were distributed into six groups (n = 60) with four replicates of 15 birds.

Fusarium head blight (FHB) is a destructive disease caused by several species of Fusarium, such as Fusarium graminearum and F. asiaticum. FHB affects cereal crops, including wheat, barley, and rice, worldwide. Fusarium-infected kernels not only cause reduced yields but also cause quality loss by producing mycotoxins, such as trichothecenes and zearalenone, which are toxic to animals and humans.

Potato dry rot is a global problem caused by Fusarium species. Symptoms of dry rot include wrinkled brown to black patches of tissue. Fusarium spp. infection in potato tubers results in the formation of mycotoxins. Fungi that cause dry rot are commonly Fusarium sambucinum and Fusarium solani.

The intestinal epithelium performs essential physiological functions, such as nutrient absorption, and acts as a barrier to prevent the entry of harmful substances. Mycotoxins are prevalent contaminants found ...

The levels of patulin contamination in fruit juices showed a discernible decline from 2014 to 2022 within the Chinese market. According to risk assessment, the average daily intake of patulin did not present a threat to public health. Summary Excessive patulin contamination in fruit juice products pose a significant risk to human health.

Postharvest pear fruits are susceptible to fungal decay and patulin (PAT) contamination during storage and transportation. PAT is a harmful mycotoxin contaminant of fruits and fruit products. Our team has identified a strain of Hannaella sinensis through preliminary research and validated its ability to degrade PAT in vitro. However, whether H. sinensis can effectively combat postharvest diseases of pears and control PAT within the fruit was yet unknown.

Physiologically based pharmacokinetic (PBPK) models were utilized to investigate potential interactions between aflatoxin B1 (AFB1) and efavirenz (EFV), a non-nucleoside reverse transcriptase inhibitor drug and inducer of several CYP enzymes, including CYP3A4. PBPK simulations were conducted in a North European Caucasian and Black South African population, considering different dosing scenarios. The simulations predicted the impact of EFV on AFB1 metabolism via CYP3A4 and CYP1A2.

Solid‐state fermentation by Aspergillus niger and Lactobacillus plantarum improved the content of bioactive compounds and physicochemical properties of wheat bran. Whole wheat bread supplemented with the fermented bran displayed enhanced textual and sensory profiles with upgraded quality. Summary Solid‐state fermentation (SSF) is an economically viable processing technique to improve the bioactive content from agricultural by‐products.

Aflatoxin B1 (AFB1) contamination is a food safety issue threatening human health globally. Biodegradation is an effective method for overcoming this problem, and many microorganisms have been identified as AFB1-degrading strains. However, the response mechanisms of these microbes to AFB1 remain unclear. More degrading enzymes, especially of new types, need to be discovered. In this study, a novel AFB1-degrading strain, DDC-4, was isolated using coumarin as the sole carbon source.

Abstract Ochratoxin A (OTA) is a type of mycotoxin commonly found in raw and processed foods. It is essential to be aware of this toxin, as it can harm your health if consumed in high quantities. OTA can induce toxic effects in various cell models. However, a more comprehensive understanding of the harmful effects of OTA on human astrocytes is required.

Mycotoxins are potent fungal toxins that frequently contaminate agricultural crops and foods. Mycotoxin exposure is frequently reported in humans, and children are known to be particularly at risk of exceeding safe levels of exposure. Urinary biomonitoring is used to assess overall dietary exposure to multiple mycotoxins. This study aims to quantify multi-mycotoxin exposure in UK children and to identify major food groups contributing to exposure.

Zearalenone (ZEN) is a prevalent mycotoxin found in grains and grain-derived products, inducing adverse health effects in both animals and humans. The in-field application of microorganisms to degrade and detoxify ZEN is a promising strategy to enhance the safety of food and feed. In this study, we investigated the potential of three actinobacterial strains to degrade and detoxify ZEN in vitro and in planta on wheat ears.

Almonds play a significant role in Iran’s economy, and factors that threaten their market, such as aflatoxins, need careful consideration. Plasma‐activated water (PAW) is a new method that has antioxidant activity and can eliminate toxins and microbial agents, making it a suitable solution for removing aflatoxins from almonds.

This study investigated the effects of varying doses of dietary aflatoxin B1 (AFB1) on the growth, intestinal health, and muscle quality of hybrid grouper. Four diets with varying AFB1 concentrations (0, 30, 445, and 2,230 μg kg−1) were used. Elevating AFB1 concentrations led to a decline in growth indexes, specifically the weight gain rate and the specific growth rate, although the survival rate remained unchanged. Morphological indicators showed a dose‐dependent decline with AFB1 exposure.

The aim of this study was to investigate the effects of aflatoxin B1 (AFB1) on cholestasis in duck liver and its nutritional regulation. Three hundred sixty 1-day-old ducks were randomly divided into six groups and fed for 4 weeks. The control group was fed a basic diet, while the experimental group diet contained 90 μg/kg of AFB1. Cholestyramine, atorvastatin calcium, taurine, and emodin were added to the diets of four experimental groups.

Patulin, a toxic mycotoxin, can contaminate apple-derived products. The FDA has established an action level of 50 ppb (ng/g) for patulin in apple juice and apple juice products. To effectively monitor this mycotoxin, there is a need for adequate analytical methods that can reliably and efficiently determine patulin levels.

Abstract Pear residue, a byproduct of pear juice extraction, is rich in soluble sugar, vitamins, minerals, and cellulose. This study utilized Monascus anka in liquid fermentation to extract dietary fiber (DF) from pear residue, and the structural and functional characteristics of the DF were analyzed. Soluble DF (SDF) content was increased from 7.9/100 g to 12.6 g/100 g, with a reduction of average particle size from 532.4 to 383.0 nm by fermenting with M. anka.

Doubled haploid lines from the cross Thatcher‐Lr34 × Thatcher‐Lr13 inoculated with Fusarium graminearum were assessed for Fusarium head blight (FHB) and deoxynivalenol (DON) accumulation. Both Lr34 and Lr67 significantly reduced FHB symptoms and DON. Abstract The resistance gene Lr34 conditions durable disease resistance to many biotrophic wheat pathogens and has been incorporated into many wheat cultivars throughout the world.

Aspergillus flavus (A. flavus), a frequent contaminant in silage, is a significant producer of aflatoxins, notably the potent carcinogen aflatoxin B1. This contaminant poses a potential risk during the initial aerobic phase of ensiling. The present work studied the impact of temperature on A. flavus growth and aflatoxin B1 production in laboratory-scale sorghum silos during the initial aerobic phase. Growth curves of A.
